Abstract

The invention relates to the technical field of underwater detection equipment, in particular to an underwater acoustic beacon, which solves the problems that when the conventional underwater acoustic beacon is used in a water area, the conventional underwater acoustic beacon is powered by a battery and cannot be automatically supplemented with electricity, so that the service life is limited, and the submergence height of the underwater acoustic beacon cannot be conveniently controlled. According to the invention, the self-power generation is performed by utilizing water flow, so that the service life of the underwater acoustic beacon can be effectively prolonged, and the diving depth of the underwater acoustic beacon can be controlled by performing inflation and deflation operations on the air bags.
